This sale is for a mint condition Mamiya RB67 Extension Tube 82mm (No.2), complete with both caps. Suitable for use on all RB67 cameras – Pro, ProS and ProSD.
There are absolutely minimal signs of use, just a tiny scuff on the mounting ring on the underside. I doubt whether this has been used more than once or twice. It has been tested and works perfectly.
This extension tube will give you 0.65 to 1.01x magnification with a standard 127mm lens.
A copy of the instruction leaflet can be downloaded from the Downloads section of this website that gives full details of usage (essential for correct exposure if you do not have a metered finder).
